Development of an embedded sensor for the measurement of resistivity in concrete. This article focuses on the development of resistivity sensor embedded in concrete and compatible with devices and test protocols used in geophysics. The goal of this work is to observe the desiccation of concrete and detect the chloride concentration during the life of the structure with the same device. The sensor and the interrogation protocols are optimized by carrying on tests on a specimen of known and homogenous resistivity. Then the optimized sensor is used to observe the hydration and drying processes of concrete.
